In the age of facial recognition, it’s not unreasonable for some to fear that bad actors could use this technology to track them. So researchers at the University of Chicago have come up with a tool to try to fix this.

Fawkes is a computer program that makes small, pixel-level changes to your pictures before you upload them to social media. And yes, the name comes from would-be assassin Guy Fawkes, best known today as the face of the V for Vendetta mask.

The changes Fawkes makes to images are so small that altered photos look almost the same to human eyes. But the changes are also significant enough to prevent third-party facial recognition from identifying the subject. The researchers hope this can help internet users protect their online privacy as it becomes easier for anyone to train effective facial recognition models.

In their paper on the software, the researchers say Fawkes “provides 95+% protection against user recognition”. They also say Fawkes tested 100% effective against some of the most advanced facial recognition systems, including Microsoft Azure Face, Amazon Rekognition and Face++ from Chinese company Megvii.

“In today’s world where big tech is becoming ubiquitous in our lives, it is clear that we cannot trust large companies to protect our privacy interests,” said Ben Zhao, professor of computer science at the University of Chicago and one of the researchers who developed Fawkes.

But is facial recognition really such a threat? The researchers point to the American facial recognition company Clearview AI as an example of why you might want to use Fawkes. Clearview’s software scrapes images form popular platforms like YouTube and Facebook without the knowledge or consent of the owners. The company’s main clients are now law enforcement agencies since it stopped selling the software to private companies earlier this year.
The researchers note that Fawkes isn’t a response to Clearview specifically. Development on Fawkes started before a New York Times story shed light on Clearview’s practices in January, they said.
